How to increase size of physics time steps (delta t) in BGE?
You can set/reduce the physics substeps, but that only works in reverse (ie 10 physics steps per frame).

But what you may actually be looking for is bge.logic.setLogicTickRate(), so your logic can go faster without increasing frame-rate.



While I have not used them, the API in 2.77 provides some control over time-flow. The one you're probably looking for is bge.logic.setTimeScale(), which allows you to scale the speed of the simulation. Bear in mind that this won't influence physics substeps, so the faster you go, the worse the simulation accuracy will be.
